Masashi Kishimoto's Naruto Exhibit - Commemorating the End of Serializationis now open at the Mori Arts CenterGallery in Roppongi Hills, Tokyo, Japan.

The gallery features the fifteen long years of the history of the series. It also has exhibits about the future of the series, highlighting the spin-off manga Naruto Gaiden: Nanadaime Hokage to Akairo no Hanatsuzuki and the movie featuring Naruto's son, Boruto, premiering on August 7.

But what seems to get the fans talking is the guestbook, where you can allegedly see what Kakashi Hatake’s face really looks like, and it is drawn by none other than Kishimoto himself.

The guestbook features the short story Shinden: Fuu no Shou, where the young Team 7, Naruto, Sasuke and Sakura, made it their "S-Rank mission" to expose Kakashi's hidden face. A mysterious photographer named Sukea overheard their conversation and offered to help the team as it would be a "big scoop" for him. All their plans failed, however, and the trio go home disappointed.

Unbeknownst to them was that Sukea was actually Kakashi himself in disguise.

After completing a mission of his own--tricking the trio, Kakashi headed home to undo his disguise, revealing a beauty mark just below the left part of his lower lip.

Note: This is read from right to left. If you can read it, anyway.

The name "Sukea" most probably came from the word "scare," which forms the compound word "scarecrow," which is "kakashi"in Japanese.

Well played.

And by the way, finally, yep--mystery solved.

There is another short story entitled Shinden: Rai no Shou, telling a story from Kiba Inuzuka's dog Akamaru's point of view.
